TraceTogether supports Singapore’s efforts to fight the spread of COVID-19 through community-driven contact tracing.

TraceTogether notifies you quickly if you’ve been exposed to COVID-19 through close contact with other TraceTogether users. The app allows the Ministry of Health (MOH) to give you timely care and guidance, protecting you and those around you.

The app uses Bluetooth, and your Bluetooth data is stored securely on your phone. It’ll be shared with MOH if you test positive for COVID-19, for the purpose of contact tracing. Also, all Bluetooth data stored on your phone is automatically deleted after 25 days.

TraceTogether helps us ensure that we don’t spread the virus to our loved ones unknowingly. It also helps us support the work of contact tracers and healthcare workers by combating the spread of COVID-19 together.

App functionality will cease once the outbreak ends.

TraceTogether is designed for use by people in Singapore. To register, you will need a valid NRIC, FIN, or a valid document of your current stay in Singapore.

What’s New

Version 2.7.2

- Fixed a display issue with COVID health status
- Improved the error messages displayed when there are issues with SMS OTP

What else is new in 2.7:
- The TraceTogether friends exercising in the park have made space for you to view your vaccination status!
- We improved the speed of QR detection, especially when the QR code is far away
- New users can receive their SMS One-Time Pin (OTP) more reliably
- When choosing family members for a Group Check-in, you can tap the entire row instead of just the checkbox on the right. Thanks for the feedback from left-handers!

Thank you for making community-driven contact tracing possible. Take care, and stay safe! :)

It’s obsolete and annoying

I don’t know what’s wrong but every day when my our pack takes over it turns of all notifications in every app. When I my apps return my trace together app comes back but with no notification. When it give the option to turn on notifications again. The option in settings just disappears and I have to delete and reinstall the app every day because it’s compulsory in my school. In addition it expects Bluetooth to be on at all times. This causes my phone to only have battery life of 4 hours. However this app if used on a better phone without our pack app control is very useful when scanning and signing in and out. With that this app has good intentions but is exacted poorly for people with my problem

Make Favourites Faster

Update: As per my earlier review titled, “Will be 5⭐️ if can bookmark”, I have updated the review from 4⭐️ to 5⭐️. Now that favourites are in, I hope you can make it easier to access by putting it on the main screen. Currently, it takes 4 taps to go from scan->fav->select location->check-in. It will be good if you can put fav in the main screen to bring the steps down to 3 taps. Better still, it will be great if you can put the check-in button of 3 user selected locations on the main page for one tap check-ins. This will help a lot for ppl going to work in the same location every day, when we check-in in the morning, go to lunch and check-in at the hawker center, then go back office check-in again. Thanks a lot!
Good that it’s finally able to scan QR codes. Will be great if we can bookmark specific floors in a building, especially for very tall building, so that hwe can check in to office without having to scan, scroll and select every day.

Use Singpass Mobile to authenticate user

Personally I think it’s better that TraceTogether uses Singpass Mobile to authenticate users instead of asking user to enter their particulars, especially the IC date of issue. This info is very sensitive as the only means to reset Singpass account. Not that TT will be compromised, but in the event such things happens, the impact will be irrecoverable. Hence, to better reduce the risk, and additional info that is not necessary to maintain and store, pls do consider using Singpass for verification and authentication for TT app. This is precisely the reason Singpass Mobile and Verify is for. To minimise data exposure risk. Hope TT can take this seriously. Thanks.

Hi, thanks for the reply. I do know that DOI will help to prevent spoofing. Hence, I was asking why TT app is not using Singpass as the mode of verification? Thus, removing the need of this DOI requirement. I don’t think anyone can say Singpass is easily spoofable. And i am not comfortable with TT app maintaining this critical info such as DOI. Please do look into implementing Singpass as the mode of verification urgently and precisely the reason why we have Singpass in the first place. If all govt apps starts to ask for DOI to verify, it will be an identity nightmare. Thanks.

Developer Response ,

Hi, thank you for your feedback! While we understand your concern regarding Date Of Issue (DOI) in the registration process, we do however require it as a form of validation of one’s identity at the moment as this is not easily spoofed. Once again, thank you again for your valuable feedback and in the meantime, stay healthy, stay safe!
